(If X = (aij)m×n and Y = (aj)m×n be any two matrices and X + Y is defined, find the order of X + Y.)

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

step-by-step explanation:

a and d

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
